Title: Method for structuring a safe ringbus system and the arrangement for carrying out the method
Inventor: HOEGENER HANS JUERGEN DIPL ING
IPC: H04L12/437
Filed: 1988-04-23
Abstract: In this method, an additional safety bus (SB) is used. Each subscriber (T1-Tn) exhibits a bus coupler (BUKO) which consists of at least two receiving devices (E1, E2), a changeover device (US) and a transmitting device (SE). The ringbus (RB) conducts the data flow coming from the transmitting device (SE) of a subscriber to the receiving device (E1) of the subscriber directly following in the direction of data flow. At the same time, the data of the same subscriber are conducted from its transmitting device (SE) via the safety bus (SB) to the receiving device (E2) of the next subscriber but one. In a fault case, that is to say when the data flow is interrupted in the ringbus (RB), the changeover device (US) of the subscriber which is no longer receiving data switches over to its receiving device (E2). The data flow of the overall ringbus system is not interrupted, only the subscriber who has caused the interruption in the data flow or who is stationed directly in front of the fault source in the ringbus (RB) being eliminated from the ring. <IMAGE>
Patent DE-3816717-A1 (DE)
Inventor: REUFFURTH RAINER DIPL ING
IPC: B03C3/86
Filed: 1988-05-17
Abstract: In order to improve the arrangement and fixation of corona electrodes in a tensioning frame it is proposed to provide the corona electrodes with end portions which are semicircular in cross-section. This will permit the end portions of the electrodes to be joined to the tubes of the tensioning frame by welding at two points whereas the corona points need not be appreciably spaced from the electrical center.

Title: Apparatus for applying a coating
Inventor: MIURA YASUHIDE
IPC: B05C17/005
Filed: 1988-09-09
Abstract: Apparatus for applying a coating to an edge section of a plate, having a grip (1) which is provided with a guiding surface (11), which has a substantially L-shaped cross-section and corresponds closely to a rounded-off edge which is formed at the connection of the outer surface of the metal plate and the underlying surface of the edge section. A nozzle (6) is fastened on the grip (1) in such a way that it can be moved towards the guiding surface (11) and away from it in the direction of which the edge section extends. The nozzle (6) is prestressed by means of a spring (10) to a position in which the nozzle (6) comes into contact with the edge of the edge section. In the nozzle (6) there is formed a recess (12), and the edge section is received in the recess (12) in such a way that both side surfaces of the edge section are kept away from the recess (12). A slit opening (13a, 13b, 13c) is formed in the recess (12) and extends continuously in the shape of a U. The opposite edges (14a and 14b) of a section (13b) of the slit opening, which are arranged in the depth of the recess (12), are offset in the longitudinal direction of the nozzle in such a way that only the edge (14a) comes into contact with the edge of the edge section. Since the grip (1) is moved along the edge of the edge section, while a coating material is fed through the lines (18, 19), the coating material is ... onto the edge ...

Title: Frequency-phase modulation generation - using signal to pulse period converter, electronic relay, and pulse period uninterrupted transmission
Inventor: DIRR JOSEF DIPL ING
IPC: H03M11/00
Filed: 1989-03-20

Patent DE-3915024-A1 (DE)
Inventor: OBARA TSUNEO
IPC: G03G21/00
Filed: 1989-05-08
Abstract: When designing apparatus, such as a photocopier, it may be necessary to arrange for the power consumption to stay within limits imposed by available power supply, e.g. on common household lines. Once a prototype has been built, the power consumption of the overall apparatus and of individual components an be monitored and compared with target values. If it is required to reduce consumption/improve overall efficiency, a systematic approach is adopted to the modification of subsystems with continuous monitoring until the desired result is achieved. Numerous modifications are suggested, including some which depend upon the timing of the operation of power-consuming elements so that the total power drain days within the limits. <IMAGE>

Inventor: COLLETTA ANGELO
IPC: B03C3/06
Filed: 1990-02-06
Abstract: During the combustion of hydrocarbons and other fossil fuels there is often abundant emission of carbon particles (particulates), due to shortage of air in the mixture burnt or even to poor mixing. According to the invention, particulates are removed from exhaust gases by means of an electrostatic separation system which can advantageously be formed as part of the exhaust or flue gas system. The particulates collected, can be burnt in situ by introducing air, heating 5 the deposit and igniting the mixture with a spark plug 10. Alternatively (Fig 2) a demountable exhaust pipe may be used and removed for cleaning. <IMAGE>
